sToP AND WASTE COCK.

SPECIFICATION forming part of Letters Patent No. 333,368, dated December29, 1885.

Application filed November 9, 1885. Serial No.182,210. (No model.)

To all whom, it may concern.-

Be it known that I, DOUGLAS WEsrnRvELT, of Chicago, in the county ofCook and State of Illinois, have invented a new and Improved CombinedStop and WVaste Cook, of which the following is a full, clear, and exactdescription.

My invention relates to the construction of a combined waste and stopcook or valve, the

object of the invention being to supply a valve which in operation willprevent any possible escape of sewer-gas, and in which it will beimpossible to open the supply and waste pipes at the same time.

A further object of the invention is to so construct the combined valveor cock as to cause it to indicate any leak in the supply or wastevalves.

To the above ends the invention consists of certain novel constructionsand combinations to be hereinafter explained, and specifically pointedout in the claims.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a vertical sectional view of the combined stop and wastecook, the parts being represented in position to discharge water fromthe service to the waste pipe, and Fig. 2 is a similar view representingthe parts as in position to supply the service-pipe.

Referring now to the general construction as illustrated in thedrawings, A represents a casting formed with two cylindrical chambers, aand b, and a globe-shaped chamber, 0. The diameter of the upper chamber,a, is considerably more than that of the lower chamber, b, and afterbulging out from below the chamber b the chamber 0 is contracted, sothat at its lower end it is of less diameter than either of the otherchambers formed in the casting A. Three nose pieces, d, e, and f, arealso formed upon the casting, leading, respectively, to or from thechamber, a, b, and c, the supply-pipe being connected to the nose-pieced, the service-pipe to the nose-piece e, and, finally, the waste-pipe tothe nose-piecefiwhich, as shown, is below the other connecting-points.The nose-pieces named form, respectively, the supply-port s, the serviceport t, and the wasteport a.

At the lower end of the chamber a there is a rounded valve-seat, 9,while the walls of a the lower portion of the globe-shaped chamber c actas the seat for a plug valve, 1;, which is controlled by means ofa-valvestem, k, which extends upward for manipulation throughv thehollow cylindrical valvestem Z. This valve-stem Z carries two valves, mand a, the valvembeing a plug-valve, and so arranged as to fit tightlywithin the chamber a, within which chamber the valve may be raised tothe position shown in Fig. 2, or lowered to rest upon its seat 9. asshown in Fig. l. The valve n fits closely within the chamber b, thedistance between the two valves being such that the valve a will bewithin the upper portion of the chamber b when the valve m is raised toits full extent, and will not pass downward into the chamber 0 until thevalve m has entered the lower portion of the chamber u below the port 8.The upper end of the casting A is closed by a plug, 0, which isscrew-threaded to engage with a thread formed in the inner 5 face of thecasting. This plug 0 bears upon a packing-ring, p, which is supported bya washer, q, that rests upon a shoulder, r, formed above the chamber a,the cylindrical valvestem Z passing upward through a central open- 8oing formed in the plug-washer and packing.

A cylinder, D, is connected to the upper end of the casting A, and thetop of this cylinder, which reaches to the top of the lowest floor ofthe building in connection with which the improved stop and waste cockis to be used, is closed by a cap, E, centrally apertured to allow thevalve-stem Z to pass through it for manipulation.

A weight, N, which is secured to the valve- 0 stem Z, rides up and downwithin the cylinder or pipe D. A cross-piece, n, is fixed to thevalve-stem Z just below the weight N, so as to enter a slot formed toreceive it in the top of the plug 0 when the valve-stem is lowered, g5and by means of this arrangement the plug 0 may be screwed in place orunscrewed. The valve-stems k and Z may be operated in any mannerdesired. i
